FAQs About Custom Food Container Manufacturing
At Anhui iFun, we specialize in high-quality, customizable food containers and insulated jars. Below are answers to the most common questions we receive from brands, retailers, and wholesalers. If you don’t find what you need, contact our team for personalized support.
1. What materials do you offer for food jars, and which is best for my needs?
We manufacture food jars in three premium materials, each with unique advantages:
Stainless Steel (304/316 Grade):
Best for: Durability, temperature retention (6–24 hours), and eco-friendliness.
Ideal for: Hot/cold meals, outdoor use, or premium brands. Resists rust and odors.
Glass (Borosilicate):
Best for: Chemical-free storage, microwave safety, and aesthetic transparency.
Ideal for: Baby food, reheating, or brands targeting eco-conscious consumers.
Food-Grade Plastic (PP, Tritan™, BPA-Free):
Best for: Lightweight affordability and customizable colors/designs.
Ideal for: Budget-friendly lines, kids’ products, or single-use packaging.
Need help deciding? Share your use case (e.g., insulation needs, target market), and we’ll recommend the best material.
2. How long can a thermos food jar keep meals hot or cold?
Our vacuum-insulated food jars maintain temperatures for 6–12 hours (hot) and 12–24 hours (cold), depending on the model and initial food temperature. For best results:
Pre-heat/pre-chill the container before filling.
Seal tightly to prevent air exposure.
Avoid opening repeatedly during use.
3. Can I store dairy or acidic foods (like soup or fruit) in stainless steel containers?
Absolutely. Our 304/316 stainless steel is inert and won’t react with acidic or alkaline foods. For dairy, ensure the container is thoroughly cleaned after use to prevent odor retention.
4. How do I prevent bacterial growth in my food jar?
Always store food at safe temperatures: above 140°F (60°C) for hot or below 40°F (4°C) for cold.
Clean the jar immediately after use with warm, soapy water, and dry completely.
Avoid leaving moist food residue inside for extended periods.
5. What’s the best insulation technology for food jars?
Double-walled vacuum insulation is the gold standard. It creates an airless space between walls to block heat transfer, outperforming foam or single-layer designs. Our jars use this technology for maximum efficiency.
6. Can I customize the lid design (e.g., leak-proof, bamboo, or foldable handles)?
Yes! We offer:
Leak-proof silicone seals for spill resistance.
Eco-friendly lids (bamboo, PP plastic, or stainless steel).
Ergonomic additions like carrying straps, foldable handles, or dividers for bento boxes.
7. What’s the MOQ for custom food container orders?
Our minimum order quantity starts at 500–1,000 units (varies by design complexity). Smaller trial orders may be possible—contact us to discuss flexibility for startups.
8. Do you sign NDAs to protect my custom designs?
Yes. Anhui iFun respects intellectual property. We’ll gladly sign an NDA or NNN agreement before reviewing your sketches or specifications. All shared data is stored securely, and projects are handled by a dedicated manager.
9. How do you ensure consistent quality in bulk production?
We implement:
Strict QC checks at each production stage (material sourcing, molding, insulation testing, etc.).
Third-party lab certifications (FDA, LFGB, SGS) for safety compliance.
Batch sampling before shipment to verify durability, temperature retention, and finish.
10. Can you replicate a competitor’s design with modifications?
We can inspire functional improvements (e.g., better insulation, lid design) but don’t copy patented designs. Share your ideal features, and we’ll engineer a unique solution tailored to your brand.
11. What’s the lead time for custom orders?
Typically 10–25 days after finalizing designs (depending on order size and customization). Rush production may be available—ask our team for expedited options.
